Slight burning sensation in penis which goes after peeing, no cloudy urine, no foul smelling urine, frequemt urination 8 times a day. I'm virgin teen male?

This sounds like. either a urinary tract infection or irritation of the urethra (the tube that brings the urine to the outside). This could be from masturbation or tight clothing or biking. Please see your doctor so that you can get tested for a urinary tract infection. Meanwhile, drink plenty of fluids and avoid irritating activities while the symptoms are present.
